. 2 Claims.- (011555-116) This invention relates to chairs, particularlyto self adjusting chairs of the type commonly used on steamers, beaches,lawns, etc.,

An object of the present invention is to provide an improved chair ofthe above type which is easily adjustable to various reclining positionsand is capable of being folded into a very compact condition when not inuse or for transportation.

Another object of the invention is toprovide an improved chair of thecharacter mentioned, which is simple in construction, and reliable andexact in function under all conditions of service.

The invention also comprises certain new and useful improvements in theconstruction, a1"- rangement and combination of the several parts ofwhich it is composed, as will be hereinafter more fully described andclaimed.

In the accompanying drawings:-

' Figure l is a perspective of the frame of a chair constructedaccording to myinvention, the fabric portion of the back and seat beingomitted so as to show clearly the underlying structure;

Fig. 2 is an elevation looking at the rear ,of

the chair;

Fig. 3 is a vertical longitudinal section taken on the line 3-3 of Fig.2; a

Fig. 4 is an enlarged elevation of a portion of the chair frame showingthe manner in which the back and seat frame is adjustably mountedthere-- on, the seat and back frame being shownin one position by fulllines and in two other positions by broken lines; and

Fig. 5 is a rear elevation of a portion of the structure shown in Fig.4, showing the manner of pivotally connecting the back frame to theadjacent portion of the chair frame.

Referring to the drawings, the chair comprises front legs II, positionedparallel. to each other the bottom and mid points, respectively. As iscustomary, the rods I2 and I3 are rigidly fixed Near their bottom, therear legs I4 are connected by a rod l6, which is rigidly fixed in anysuitable manner to the rear legs I4.

Also pivoted to the pins I5, are the front ends 55 of arm rests I'I.These arm rests extend rearand connected by parallel rods I2 and I3near' A pair of rear legs I4 are pivoted, by bolts or wardly, and, as iscustomary, lie in a substantially horizontalplane'when the chair is setup.

The rear ends of the arm rests I! are supported from the rear legs I4 bybrace members I8. The upper ends of the braces l8 are pivotally. 5connected to the rear ends of the arm rests ll by bolts or pins I9, andthe lower ends of the braces are'connected by a rod 20.

shown in Fig. 2, the rod 20 is mounted in openings 2! formed through thebraces l8, and 10 the ends of the rod 20 project a suitable distancebeyond the braces I8,*as indicated at 22. g The rod 20 is rigidly fixedto the braces in any suitable manner, such as by nails 23.

Formed in' each of the rear legs I4, at a suitable distance above therod I6, is a notch 24. The projecting ends 22 of rod 20 are. adapted toseat inthe notches 24Yto retain the frame of the chair in position asshown; 7

' At a suitable distanceabo-ve the rod 20, a sec: 4 0nd rod 25connectsthe braces l8, being rigidly fixed to said braces in any suitablemanner. The rods 20 and 25 are disposed substantially parallel, however,rod '25 does not project beyond the braces I8.

Mounted on rods l3 and 25, and disposed adjacent tothe'legs II and I4,are seat supporting members in the form of bars 25.

The bars 26 are positioned adjacent the inner surface of the legs I I,and the brace members 18 3 are interposed between the outer surface ofthe bars 26 and the inner surface of the rear legs IA. The arm restsl'l'are positioned against the outside surfaces of the rear legs I4 andbrace membersI8'. This arrangement permits the framework to befoldedwhen the rod 20 is lifted out of thenotcheszl, I

The-seat comprises a frame composed of side rails 21 which are connectedat thefrontby a r0d'28, andconnected at the rear by a rod 29. 4c

The seat supporting bars 26 are arranged substantially parallel and thesiclerails 27 of the seat are also parallel and are superposed on thebars 26' was to be wholly supported thereby, as shown in Figs. 1,; 3,and 4. The side rails 27 are slidably mounted onthe' supporting bars26for forward and backward movement, and in its forward and backwardmovement the relative position of the seat with respect to the frame ofthe V chair and especially the supporting bars 26 never changes. That isto say, since the seat frame rests on and is supported wholly by thebars 26, and said bars 26 are stationarilyheld in the chair frame whenthe chair is set-up, the side rails 21 of the seat frame will alwaysremain in a subconnected, at a point adjacent their upper ends,

by a rod 3!. v

The back is supported from the arm rests H;

by means of link devices 32, so constructed as t plurality of to permittilting of the back in 2. positions.

As shown best in Figs. 4 and 5, each linkdeyice 32 comprises anelongated member-, preferably formed from metal, and having an offsetand laterally projecting upper end portion 33, which is formed with aperforation by which the link is mounted on pivot pin 19.,

A slot 34 is formed in the main body portion of link 32 in which isdisposed a pin 31fcarried by each side member 30 of the back. fInlieu ofpin 31 any other equivalent member or device may be employed forconnecting the side member 30 to link 32.

The upper end of slot 34 is formed with a notch 35 which extendsoutwardly with respect to the slot. Intermediate of the slot 34, thereis another notch 36 which also extends outwardly.

As shown in Figs. 1 and 4, when the back is in a slightly inclinedposition, the link devices 32 project outwardly from pivot pins I 9 andnotches 35 and 36 are disposed on the upper edge or upper side of theslots 34, in position to receive pin 31. When the back is lowered to amore reclined position, pin 37 will be disposed inthelower ends 38 ofslots 34. position in the notches, due to the downward pressure exertedby the weight of the links 32, it being understood that said links 'areloosely pivoted on the pins l Qand normally tend to hang verticallydownward from the pins l9.

The chair may be quickly folded into a fairly compact bundle fortransportation or storage" by simply lifting rod 20 out of the notches24 andforcing the legs together. The particular construction describedabove, due to the arrangement of the various parts, takes up acomparatively small floor space when'set up or when folded.

As shown in Fig. 4, repositioning of the back as above described,effects a simultaneoeus sliding movement of the seat frameupon'supporting' bars 26, and in sliding forwardly and backwardly on thebars 25, the side rails 2'. f the seat frame will, at all times, restupon the bars 26, irrespective of the position of the back frame of thechair.

This is due to the loose pivotal connection of the back with the armrests l1, provided by link devices 32 and their associated parts.

As shown in Fig. 3, extending from front seat rod 28 to upper back rod(i l and fastened to said rods and also to rod 25, is a' strip ofsuitable fabric, such as canvas, duck, orthe like. This The pins 3? willbe retained in canvas provides a seat 40 and a back support 4 for anoccupant of the chair. I

The glide of the seat is limited by means of a. loop member 42, fastenedto front seat rod 28 and looped around rod l3, as shown in Fig. 3. Loopmember 42 may be formed from any suitable flexible material or fabric,such as canvas, duck, and the like.

The relative positions of the seat and back of the chair may be quicklyshifted by simply lifting the link devices 32 so as to move the pins 31out of the notches in said link devices in which they are disposed andrepositioning the pins .31 in other notches of the link devices 32. Fig.4 illustrates several positions in which the back can be set by shiftingthe links 32, as above described, and such movement of the back effectsa corresponding shifting of the seat on its supporting bars 26.

Changes may be made in the details of construction and in thearrangement of the parts above described within certain limits withoutdeparting from the. spirit of the invention.

Having thus described my invention, what I claim is:-

l. A chair of the type described comprising pivotally connected frontand rear legs, arm rests also connected to said leg pivots, bracemembers pivotally connected to said arm rests and detachably connectedto the rear legs near the lower ends thereof, substantially horizontallydisposed seat supporting bars connected to said front legs and to said,brace members, pivotally connected back and seat frames of which thelatter restswholly on said seat supporting bars, said seat frame beingadapted to slide forwardly and backwardly on its supporting bars withoutany part separating therefrom, links pivotally connected to the armrests, pins projecting from the back frame, slots formed in said links,and notches formed in said slots for receiving said pins for retainingthe backframe in a'plurality of positions. f

2. A chair of the type described comprising pivotally connected frontand rear legs, arm rests also connected to said leg pivots, bracemembers pivotally connected to said arm rests and detachably connectedto the rear legs, substantially horizontally disposed seat supportingbars connected at their rear end to said brace members, a tieredconnecting the front legs for supporting the forward ends of said seatsupporting bars, pivotally connected back and seat frames of which thelatter is slidably mounted on said supporting bars whereby saidseat'frame is disposed in a substantially fixed horizontal position atall times, links pivotally connected to the arm rests, pins projectingfrom the back frame, slots formed in said links. and having meanstherein for receiving saidback frame pins for retaining the back framein a plurality of positions, and a loop memberncarried by the seat frameandlooped around said tie rod for limiting the movement of the seatframe on its supporting bars.
